and have some questions in my last post regarding medium format which I hope you could correct/confirm for me.

Now heres the interesting question. If we fix the enlargement size to 8x10.. how much can we push a 6x7 negative for it to still achieve the same resolution as the 35mm negative? Lets say its two stops since theres 4 times as much film. Im also asumming that a 80mm lens on MF will still only require 1/50 since its the normal lens for MF and so movement has the same angular resolution effect. Someone please answer this.
